LONDON, England (CNN) -- British singer Amy Winehouse entered a rehabilitation clinic Thursday as part of her ongoing battle against drug addiction, her record label said.

The cover of British tabloid The Sun shows a video still of Amy Winehouse smoking a glass pipe.

"Amy decided to enter the facility today after talks with her record label, management, family and doctors," the Universal Music Group said in a written statement. "She has come to understand that she requires specialist treatment to continue her ongoing recovery from drug addiction and prepare for her planned appearance at the Grammy Awards. ... Amy entered the facility by mutual agreement and continues to receive the full support of all concerned."

Because she entered the clinic, Winehouse's scheduled appearance at an awards show in France on Saturday was canceled, the statement said.

Her decision followed the leak earlier this week of a home video that showed her smoking something in a glass pipe minutes after she is heard saying she had just taken six tablets of the anti-anxiety drug Valium. Watch the video of Winehouse and a glass pipe »

The Sun, Britain's best-selling daily tabloid newspaper, made the 19-minute video public on Tuesday. It said it was shot the previous Friday in Winehouse's East London home. The Sun posted an edited version of more than two minutes on its Web site.

In the video posted online, Winehouse walks around her home in a dark tank top, talks to a friend on her cell phone, and talks to the person shooting the video.

At one point, Winehouse says, "I just took about six Valium."

Sitting on her bed, she then lights a glass pipe and inhales. What was in the pipe was unknown.

On Wednesday, Scotland Yard said it was looking into the video after receiving it from The Sun.

Winehouse has become famous for her battles with addiction. Her hit song "Rehab" describes her reluctance to enter a rehabilitation center. She previously entered rehab last summer.

In October, Winehouse and her husband, Blake Fielder-Civil, were arrested at a Norwegian hotel for marijuana possession, and soon afterward fans booed her on stage as she slurred and stumbled her way through her gigs.

In December, tabloids published pictures of Winehouse with a mystery white powder in her nose. She was also photographed wandering barefoot on a London street, wearing only jeans and a bra and appearing disoriented.

Fielder-Civil is currently behind bars in London on charges of perverting the course of justice following a bar fight.

Her parents have publicly expressed concern that their daughter is succumbing to the pressures of fame.

Winehouse received six nominations for next month's Grammy Awards, including record and song of the year for "Rehab" and best album for "Back to Black."

"Amy is the most talented and important musical artist of her generation and has made huge strides on her road to recovery," the record label's statement said Thursday. "Universal Music Group wants nothing more than to see her take the time she needs to come back to full health and fulfill her incredible potential with the label."E-mail to a friend
